This invention relates to wall structures and has for its primary object to provide an improved form of construction comprising blocks of right angled isosceles triangle shape in plan, in which the right angled edges of the triangle are chamfered and the blocks are placed so that succeeding hypotenuses are on opposite sides of the wall and water resisting material is introduced into the tapering ap- 10 ertures between adjoining blocks.

A further objectof the invention is to provide a hollow block for use in wall construction having for external shape on plan a right angled isosceles triangle and provided at the bottom with depending lips, and at the top with corresponding recesses to form rainresisting horizontal joints. 1 I v With these and other objects in view, the in- I V vention consists in the improved blocks and p wall structures heremafter described in detail, the novel features of which are 'set out in the accompanying claims.

r In the preferred form of construction employing blocks of this shape, the blocks on the outer surface of the wall ofa building are formed of hard impermeable concrete while the blocks on the inner surface of such wall are formed of porous concrete; the outer surface of the wall is therefore able to I'BSlSlT 1n- 7 30 gress' of rain while the inner surface is a bad conductor of heatand thus ensures absence ofwith the present invention the blocks are formed with chamfered edges at the right angle apex and waterproof vertical damp courses are provided to prevent ingress of water to the porous blocks. I

The acute-angled edges of the blocks which abut the chamfered right-angled edges of the blocks on the other side are preferably also chamfered thus leaving a space between the lustrate the invention,

edges.

abutting blocks which first reduces in width and then increases and the vertical damp- I course materialis introduced into this space. 1

In the accompanying drawings which .il-

a 1 a Fig. 1, represents a sectionalplan of a portion of a wall containing a corner, employing vertical damp coursesofsheet material, i Fig. 2 represents a corresponding sectional, plan at an'alternatecourse; c Fig. 3 represents to enlarged scalean eX- ternal joint. f N v v l Fig. 4 represents a cross-section illustrating a depending lip to prevent ingress of water at I the horizontal joint.

In Figs. 1 and 2 [external impermeable blocks are indicated by close vertical shading" 7 lines While porous blocks are indicated by 7 more widely spaced horizontal shading lines in these figures the preferred form of hollow block.each block comprising one substane tially square cavityand two triangular cavities is illustrated andis to be understood that it is preferred to provide similar cavities in the blocks illustrated in the'other figures. In the drawings the vertical damp course is shown on the outer or weather surface of the v wall only but I Wish it to be understood that a similardamp course may be provided on both sides ifpreferred. "Referring first to Figs. 1 to '3 the wall is 1 built up of impermeable blocksA on the out side of the wall and porous blocksgon the inside, the blocks beingof section on'plan right- I angledisosceles triangles with the edge at the right angle formed with a chamfer C.

Smaller chamfers are formed at the other On alternate courses halfbloclisA B 'are employed at the corners to give true bond1ng;-

each of these blocks is geometrically similar .to the larger blocks. The vertical damp course in the form illustrated in these figures is provided by metal strips D which bear against thev chamfered edges 0 of the porous blocks; the edges d of the strips areturned loacl; as shown clearly inFigure 3to close the gap between the blocks As will be seenfromthe figures this leaves a space F between the blocks with afnarrow g portion ashort distance in and this space is then filled with pointing mortar.

Although strips of metal are preferred they niay also be of any other impervious material' pending lips Hon their lower surfaces and p corresponding grooves J ontheir uppersur faces thus breaking the horizontal joint; and the ends (1 (Z of the strips are bent over asshowu. v 7

It is to beunderstood'that the invention is not restricted to'the exact details shown and described but embraces such modifications as come within the 'a-mbit'of the accompanying claims. V

I claim 1. A wall structure comprising in a horizontal course blocks of horizontal triangle shape in plan with chamfered edges'so arranged that thehypotenuses of' s'ucceeding blocks are onopposite sides of the wall, vertical damp"course strips placed at external vertical joints abutting t-hecham-fered rightangled apex of blocks having hypotenuscs facing internal surface of the wall; and dampproof plastic material filling the space between adjoining blocks and abutting the damp course, strips.

2. A wall structure comprising in a. horizontalcourse blocks of horizontal triangle shape in plan with cliamfered edges so arranged that the liypotenuses of succeeding blocks are onopposite sidesof the wall, vertical damp course stips placed tit-external vertical joints abutting the chainfered rightangled apex of blocks having ,hypotenuses facing internal surface of the 'wall, bent up portions of said strips abutting the inclined sides of blocks having hypotenuses facing external surface of the wall, and damp-proof plastic material filling the spacebetween adranged that the hypotenuses of succeeding blocks are on opposite sides of the wall, the blocks forming the outside facing of the wall being of impermeable concrete and the blocks forming the inside facing of the wall being of permeable concrete, and comprising also I water-resisting plastic material inserted in the space between imperl'neableblocks QClJOlH- ing'a-t their acute angles and the chamfered -righ-t angle of the permeable block lying between said adjoining,impermeable blocks, said space first reducing in width and then In testimony whereof I aifix my signature.
